**rancher-vcluster** is an *experimental* add-on. It is not included in the Harvester ISO, but you can download it from the [experimental-addons repository](https://github.com/harvester/experimental-addons). For more information about experimental features, see [Feature Labels](../../getting-started/document-conventions.md#feature-labels).

**rancher-vcluster** is deprecated in Harvester v1.9.0. Use the [**rancher-k3k** add-on](./rancher-k3k.md) instead.

Please create a ticket to remove vCluster from Harvester 1.10.0.


The add-on provisions a nested K3s cluster in the `rancher-k3k` namespace and deploys Rancher onto it. During installation, the add-on syncs the Rancher ingress to the Harvester cluster, providing user access to the Rancher UI and API.
